[0035] like Figure 1-Figure 21As shown, a base structure of a foldable children's bed includes a frame 100 formed by a plurality of upper cross bars 110 and corner members 120 to form a fence, a column 130 is provided at the bottom of the corner member 120, and a leg 131 is provided at the bottom of the column 130, a base 200 is provided at the central bottom of the frame 100, and four lower cross bars 210 for connecting the base 200 and the leg 131 and forming an X-cross structure are provided, the frame 100 is folded by moving the base 200 upward, a lifting device 300 for adjusting the upper cross bar 110 up and down is provided on one side of the frame 100, a card slot 121 for installing a hook 400 is provided on the corner member 120, and a folding member 150 is also provided on the upper cross bar 110, in order to cooperate with the folding of the entire playbed, the specific folding can refer to the patent with publication number CN106667140B, which is called "a portable playbed", and the drawings in its specification have vividly shown the folding state of the playbed, which will not be repeated in this application, and the detailed usage method is as follows.

[0036] The lifting device 300 includes a vertical rod 310 arranged at the bottom of the corner member 120, and a plurality of limiting holes 311 are provided on the vertical rod 310 and / or the corner member 120, and also includes a slider 320 for assembling the upper crossbar 110, and a clamping device 330 is provided on the slider 320 to cooperate with the limiting holes 311. The slider 320 is slidably matched with the vertical rod 310, and the position of the limiting holes 311 is switched by the clamping device 330 to adjust the upper crossbar 110. The reason why the upper crossbar 110 can be lowered is to allow the playbed to be close to the adult's bed when the bed surface 500 is laid, so that it is convenient for the baby to get off the bed surface 500. 00 can climb onto the adult bed, which is also convenient for adults to take care of the baby. The slider 320 realizes the up and down movement of the upper cross bar 110 by adjusting up and down. The limiting holes 311 are generally arranged in two groups, corresponding to the play bed mode and the combined bed mode. When in the play bed mode, the slider 320 is located at the top, and the fence is the highest at this time. The baby can play in the play bed and is prevented from climbing over, with a high safety factor. When it needs to be used as a bed, the bed surface 500 is placed on it, and then the slider 320 is moved downward and fixed with the clamping device 330 through the limiting holes 311, so that a structure combining large and small beds is formed, which is convenient for parent-child activities and adults to take care of babies.

[0037] The vertical post 310 and / or the corner member 120 are provided with a first guide groove 312 arranged in the vertical direction, and the slider 320 is provided with a guide block 321 that cooperates with the first guide groove 312. The slider 320 and the vertical post 310 are slidably matched through the cooperation between the guide block 321 and the first guide groove 312. The slider 320 is inserted into the first guide groove 312 by the guide block 321 to achieve sliding cooperation with the vertical post 310.

[0038] The guide block 321 is provided with a blocking portion 322 for preventing the slider 320 from escaping from the vertical rod 310 along the notch direction of the first guide groove 312. The slider 320 is inserted into the first guide groove 312 through the blocking portion 322, and the limited sliding cooperation with the vertical rod 310 is achieved through the cooperation of the guide block 321. The addition of the blocking portion 322 prevents the slider 320 from escaping from the first guide groove 312 along the notch direction of the first guide groove 312, thereby improving the structural stability of the sliding cooperation.

[0039] The upper part of the vertical pole 310 is provided with a protrusion 313 for preventing the corner member 120 and the vertical pole 310 from rotating relative to each other. The bottom of the corner member 120 is provided with a groove 122 for matching the protrusion 313. The corner member 120 and the vertical pole 310 are limited by the cooperation between the protrusion 313 and the groove 122. Increasing the cooperation between the protrusion 313 and the groove 122 strengthens the connection stability between the corner member 120 and the vertical pole 310, so that the first guide groove 312 on the column 130 and the corner member 120 can be positioned.

[0040] The corner member 120 and the vertical rod 310 are both provided with a limiting groove 123 that matches the column 130. The corner member 120 and the vertical rod 310 are respectively sleeved on the outside of the column 130 through the limiting groove 123 and fixedly connected by fasteners. The corner member 120 and the vertical rod 310 are both sleeved on the outside of the column 130 for easy assembly. The fasteners can be screw structures, etc.

[0041] The clamping device 330 includes a clamping block 331 that cooperates with the limiting hole 311. The slider 320 is provided with a second guide groove 323 for the reciprocating movement of the clamping block 331. The clamping block 331 reciprocates through the second guide groove 323, and the end of the clamping block 331 is clamped into the limiting hole 311 to achieve the limitation of the slider 320. The outer surface of the slider 320 is provided with a shell 325. For the convenience of understanding, the slider 320 and the shell 325 are collectively referred to as the slider 320 in this application. The clamping block 331 and the limiting hole 311 limit the slider 320 on the column 130, which means the limitation of the upper cross bar 110. The clamping block 331 realizes the upper and lower limitations of the upper cross bar 110 by switching the position of the limiting hole 311, that is, the conversion between the game bed mode and the building bed mode.

[0042] The block 331 is provided with an inclined surface 332 for forcing the block 331 to disengage from the limiting hole 311. A button 340 is provided in the slider 320. The button 340 is provided with a guide surface 341 that cooperates with the inclined surface 332. The slider 320 releases the limit through the relative movement of the button 340 and the block 331, and through the cooperation between the inclined surface 332 and the guide surface 341. Due to the cooperation between the inclined surface 332 and the guide surface 341, the block 331 is disengaged from the limiting hole 311 when the button 340 presses against the block 331.

[0043] A first elastic device 333 for forcing the block 331 to fit into the limiting hole 311 is disposed in the second guide groove 323 . The first elastic device 333 and the second elastic device 216 may adopt a spring structure, which is convenient for assembly and low in cost. The first elastic device 333 enables the block 331 to fit into the limiting hole 311 elastically.

[0044] The slider 320 is provided with a locking block 350 for preventing the button 340 from releasing the limit of the slider 320. The slider 320 is provided with a third guide groove 324 for the locking block 350 to reciprocate. The button 340 is provided with a locking groove 342 that cooperates with the locking block 350. The button 340 is limited in the slider 320 by the locking block 350 being snapped into the locking groove 342. The addition of the locking block 350 is equivalent to giving the button 340 an insurance function to prevent the baby from operating it accidentally, which greatly improves the safety. The locking block 350 is snapped into the locking groove 342 so that the button 340 cannot move the card block 331.

[0045] Both ends of the corner component 120 are provided with storage grooves 124 for folding the upper cross bar 110, and the upper cross bar 110 is rotatably connected to the storage grooves 124. There is a drooping surface 125 facing the internal space of the frame 100 between the two storage grooves 124, and the card slot 121 is arranged on the drooping surface 125. The addition of the card slot 121 actually has many functions, not just one function of increasing the bed surface 500. In addition, many toys and other decorations can be hung, which is very practical. Since one side of the children's bed has a lifting function, the corner component 120 at one end has storage grooves 124, and on the side with the lifting function, the storage grooves 124 are respectively located on one side of the corner component 120 and the slider 320.

[0046] The top of the slot 121 is provided with an upper notch 126 for the hook 400 to be loaded into the slot 121 from top to bottom. The hook 400 is loaded and unloaded in the slot 121 through the upper notch 126. The hook 400 is hung downward from the upper notch 126.

[0047] A hook 400 is installed in the slot 121, and a side slot 127 connected to the interior of the slot 121 is provided on one side of the upper slot 126. The hook 400 has a snap-fitting portion 410 that passes through the interior of the slot 121 and the side slot 127. The hook 400 is inserted into the slot 121 through the snap-fitting portion 410 to achieve position limitation on the slot 121. Adding the side slot 127 and the snap-fitting portion 410 increases the lateral bearing capacity of the hook 400, improves the supporting force of the bed surface 500, and facilitates the insertion of the hook 400.

[0048] The engaging portion 410 is provided with a stopper portion 420 to prevent the hook 400 from escaping from the side notch 127 . The hook 400 is limited in position within the slot 121 by the cooperation of the stopper portion 420 . The stopper portion 420 prevents the hook 400 from escaping from the slot 121 at the side notch 127 of the slot 121 .

[0049] The width of the side notch 127 gradually increases from the inside to the outside, which can facilitate the insertion of the hook 400.

[0050] The hook 400 is provided with a through hole 430 . The hook 400 has many structural forms, and the present application preferably adopts the structural form of the through hole 430 .

[0051] The bed surface 500 includes a bed surface 500 for supporting a human body. A connecting strip 510 is provided on the bed surface 500 for fixing with a through hole 430. The bed surface 500 is hung in the frame 100 through the cooperation of the connecting strip 510 and the hook 400. The four corners of the bed surface 500 are provided with connecting strips 510. The bed surface 500 is suspended in the frame 100 through the cooperation of the connecting strip 510 and the hook 400.

[0052] The lower cross bar 210 is rotatably matched with the base 200 . The base 200 is provided with a groove 220 for matching the folding of the lower cross bar 210 . The lower cross bar 210 is rotatably connected in the groove 220 . When folding, the lower cross bar 210 folds through the groove 220 .

[0053] The center of the base 200 is provided with an installation groove 230 for assembling the fixing seat 240, and the installation groove 230 is connected with at least one groove 220. The fixing seat 240 is provided with a switch handle 250 for opening and closing the folding of the lower cross bar 210. Not all of the lower cross bars 210 in the groove 220 are controlled by the switch handle 250, but as long as one cannot be folded, the rest cannot be folded either. The present application preferably adopts a structural form of two switch handles 250, and controls the two lower cross bars 210 on a straight line to make the structure more reliable.

[0054] The switch handle 250 is rotatably connected to the fixed seat 240, and the folding of the lower cross bar 210 is realized by rotating the switch handle 250 on the fixed seat 240. There are many structural forms of the switch handle 250, such as pressing, etc., but the present application preferably adopts a rotating matching method, which is simple and easy to use.

[0055] The switch handle 250 is provided with a stop surface 251 for preventing the lower cross bar 210 from rotating, and the end of the lower cross bar 210 is provided with a matching surface 211 that matches the stop surface 251. In the locked state, the switch handle 250 achieves rotation limitation of the lower cross bar 210 by blocking the matching surface 211 with the stop surface 251. The cooperation between the stop surface 251 and the matching surface 211 enables the switch handle 250 to firmly clamp the lower cross bar 210. Due to the principle of leverage, the lower cross bar 210 needs a lot of force to break through the stop surface 251 and the matching surface 211. Therefore, the restrictive relationship between the stop surface 251 and the matching surface 211 enables the switch handle 250 and the lower cross bar 210 to have a very stable structural relationship.

[0056] It includes a limit block 212, and the lower cross bar 210 is provided with a fourth guide groove 213 for the reciprocating movement of the limit block 212. The matching surface 211 is set on the limit block 212. The lower cross bar 210 realizes rotation limitation through the limit block 212 and the switch handle 250. The limit block 212 at the end of the lower cross bar 210 is movable, so that the lower cross bar 210 can be folded.

[0057] The switch handle 250 is provided with a protrusion 252 for facilitating the limit block 212 to retract into the fourth guide groove 213, and the limit block 212 is provided with a transition surface 214 that matches the protrusion 252. When the protrusion 252 rotates with the switch handle 250 and forces the limit block 212 to retract into the fourth guide groove 213, the matching surface 211 of the lower cross bar 210 disengages from the stop surface 251 to achieve the conversion from the locked state to the unlocked state. During the rotation of the switch handle 250, the stop surface 251 first leaves the matching surface 211, and at the same time, the protrusion 252 on the switch handle 250 causes the limit block 212 to retract into the fourth guide groove 213, and the protrusion 252 also causes the limit block 212 to retract into the fourth guide groove 213 through the transition surface 214.

[0058] The lower cross bar 210 is rotatably connected to the fourth guide groove 213 through a pin shaft 215. A second elastic device 216 is provided on the limit block 212 to force the limit block 212 to move in the direction of the switch handle 250. The limit block 212 elastically extends out of the fourth guide groove 213 through the cooperation of the second elastic device 216. The addition of the second elastic device 216 makes the limit block 212 have elastic restoring force.

[0059] The switch handle 250 is provided with a boss 253, and the fixing seat 240 is provided with a groove 241 that matches the boss 253. The switch handle 250 and the fixing seat 240 are rotationally matched by inserting the boss 253 into the groove 241. The switch handle 250 and the fixing seat 240 are rotationally matched by the matching of the boss 253 and the groove 241.

[0060] The fixing seat 240 is fixed and limited in the installation groove 230 by a tight fit. There are many ways to fix the fixing seat 240 and the installation groove 230, and the present application preferably adopts a tight fit to facilitate assembly.

[0061] Directions:

[0062] The frame 100 itself has a mesh or other fabric inside, which is not shown in the figure. When the frame 100 is fully opened, the frame 100 presents a scene in the playbed mode. Due to the existence of the fence, the baby cannot climb out, and the baby can play safely in the middle. Figure 1 shown.

[0063] When it is time to sleep, the hooks 400 on the four corners of the bed surface 500 are hung on the card slots 121, and the playbed mode is converted into the rest mode.

[0064] When the bed needs to be joined, the slider 320 is moved downward so that the lower crossbar 210 on one side is lowered to a height similar to that of an ordinary adult's bed, so that the bed surface 500 can be joined with the adult's bed, which is convenient for parent-child activities and caring for babies. Figure 2 shown.
